I have noticed on some aircraft, when in spot plane view, the wing for example is right up in my face and the rest of the plane looks far away, or the same case for other parts of the plane. Why is this?

Folks, the problem can occur on "pure" FS2000 models as well - the culprit is called "Z-Buffer" and represents the "view depth", i.e. how far away the part is from the viewers point. Mostly it is automatically computed by the flightsim, but also it can be tweaked and the automatic computed value bypassed when designing the plane and compiling the MDL. FS2k designers use this option often for collecting ugly seams between 2 parts or fight bleedthrough problems.
